This asteroid is orbiting the Sun at a distance of 3.19 AU with a low eccentricity of 0.085 and an orbital period of 5.71 years. The orbital period is inclined at an angle of 10.7° to the plane of the ecliptic. It is spinning with a rotation period of 42.49 hours.[2]
Measurements made with the IRAS observatory give a diameter of 106.08±0.25 km and a geometric albedo of 0.03±0.01. By comparison, the MIPS photometer on the Spitzer Space Telescope gives a diameter of 105.32±11.11 km and a geometric albedo of 0.03 ± 0.01.[4]
On April 15, 2005, UT Magdalena occulted a 10.7 mag star in the constellation Scutum for observers along a path across Australia.
Alternative rock group The Pixies named one of their songs after the asteroid on their album Indie Cindy.[5]
